| 摘 要： | 针对Turbo乘积码译码延时的问题,提出一种基于校验子的Turbo乘积码译码算法(S-TPC),该算法根据校验子的值采取不同方式对每行(列)进行译码,节省了一部分校验子为0的码字的硬判决译码运算量。仿真结果表明,S-TPC(32,26)在迭代4次时,能在不降低译码性能的情况下,减少近50%的计算量。

| Abstract: | This paper analyses the basic principle of Turbo product code,by choosing different block codes,iterative numbers and test sequence numbers for TPC decode performance to experiment simulation,an optimal TPC decoding scheme with high performance and low complexity is proposed.The simulation results indicate that the optimal TPC decoding scheme can get the code gain of 6 dB. |
